The purpose of this work was to investigate the bone-like apatite inducement ability of alkali and heat treated Ti-6Al-4V alloy in the HANK solution, with variation of concentration of NaOH solution and heat treatment temperature. The characterization techniques such as Scanning electron microscopy (SEM), X-ray diffraction (XRD), were selected for the evaluation of chemical composition, morphological and crystallinity properties of alkali and subsequent heat treated Ti-6Al-4V alloy. From the XRD analysis it was found that the hydroxyapatite inducement ability increased with the increments of treating temperature, while reduced with increments of concentration
